Lack of trouble shooting information

Temperature and pressure readings can organize your trouble shooting efforts when dealing with a problem in the compressed air system. Specifically, you can use normal condition readings as a reference point in order to isolate the cause of the problem. The normal condition readings are taken on a regular basis for historical reference and to observe any trends that indicate the beginning of a problem. The readings are usually taken at locations before and after air equipment including, among others, the compressors, after coolers, dryers, receivers, air tools and filters.

1. Increasing temperature in a compressed air system is one of the best indicators of a problem. If you monitor temperatures over time, you can build a base line for normal conditions and create a model for predicting when you will have trouble with your compressed air equipment. The most useful tool for this application is an infrared thermometer. This is a hand held device that gathers temperature readings by aiming at an object. There are a couple of points to keep in mind on this issue. The first is to be aware that you are measuring the surface temperature, not the temperature of the oil, air, or water inside the object. This method is not as accurate as putting a probe in the oil, air, or water. However, it is a practical way to get information that can be used in troubleshooting. The second point is to always take temperature readings when the compressor is at full load. This gives you meaningful information that can be compared to the design standards for the equipment.
2. Monitoring pressure is another useful trouble shooting tool. The best idea we observed was the use of a single gauge that was adapted to fit in an air line quick connection. The operator simply inserted the gauge into quick connections that were mounted in key locations on the air system piping. Accuracy is critical when comparing readings and trying to isolate a problem. It is important that you use a high quality gauge.
